Getting error "Failed reading APM server info" while connecting to ElasticAPM

Question

I have a .net project. I am trying to add Elastic APM Configuration in it. Below are the configurations I have added:

Program.cs:

CreateWebHostBuilder(args).UseAllElasticApm().Build().Run();

Startup.cs:

app.UseElasticApm(Config); (Config is of type IConfiguration)

I have added the spans in my controller as below:

        [HttpGet("filterValues")]
        public async Task<ActionResult> GetReportFilterTenant()
        {
            var span = _tracer.CurrentTransaction?.StartSpan("predictive-reporting", "ControllerA", "GetFilter","Getting Filter");

            try
            {
                var filterValues = _dataAccess.GetFilters();
                return Ok(filterValues);
            }
            catch (Exception e)
            {
                span?.CaptureException(e);
                Console.WriteLine(e);

            }
            finally
            {
                span?.End();
            }

            return null;
        }

I have added the below nuget package in my csproj:

 <PackageReference Include="Elastic.Apm.NetCoreAll" Version="1.22.0" />

But, the APM service is not coming up and I am not able to see the logs as well. Also, I am getting the exception below:
